Does the use of bioprosthetic valves compared to mechanical valves affect life expectancy in patients undergoing aortic valve replacement?
Bioprosthetic aortic valves can be implanted in patients as young as 56 years without significant adverse effects on overall life expectancy compared to mechanical valves, supporting a lower age threshold for their use.
Stoica et al. (2010) studied this question.
